Cladia is a genus of lichenized fungi in the family Cladoniaceae. Cladia species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Taxonomy
Cladia was circumscribed by Finnish lichenologist William Nylander in 1870 with Cladia aggregata as the type species.[3] Rex Filson created a separate family, the Cladiaceae, to contain the genus,[4] but this is no longer used and the genus is classified in the family Cladoniaceae.[5] An updated phylogeny of the Cladoniaceae was published in 2018.[6]
Molecular phylogenetic evidence showed that the genera Heterodea and Ramalinora were nested within Cladina,[7][8] so they are now synonyms. Because the name Heterodea predated Cladina, the generic name Cladia was proposed for conservation against Heterodea to avoid several nomenclatural changes that would have been necessary.[9][10] The proposal was accepted by both the Nomenclature Committee for Fungi and the General Committee.[11][12]
Description
Cladia consists of fruticose lichens with typically a perforate pseudopodetia with an external cartilaginous layer. The apothecia are black or brown and have a persistent proper margin and a flat disc. The asci are eight-spored with a well-developed amyloid tholus with a darker-staining central tube. The pycnidia are immersed in grossly black to brown projections that are initially blunt and measure up to 0.5 mm long and eventually become needle-like and up to 1 mm long.[13]
Ecology
Eight species of lichenicolous fungi are known to grow on Cladia:[14] Echinothecium cladoniae Keissl. nom. nud. (on C. aggregata from Columbia; Etayo 2002), Lichenoconium echinosporum D. Hawksw. (on C. muelleri from Australia; Hawksworth 1977), Roselliniella heterodeae Matzer & Hafellner (on C. muelleri from Australia; Matzer & Hafellner 1990); Pyrenidium actinellum Nyl. agg. (on C. aggregata from Columbia; Etayo 2002); Endococcus cladiae Zhurb. & Pino-Bodas; Lichenopeltella soiliae Zhurb. & Pino-Bodas, and Lichenosticta hoegnabbae Zhurb. & Pino-Bodas.
Chemistry
The type species, Cladia aggregata, is highly variable morphologically and has extensive chemical variation.[15] Kantvilas & Elix (1999) revised the C. aggregata complex in Tasmania and identified six chemotypes in C. aggregata sensu stricto.[13] Similarly, five chemotypes were found in specimens from the states of Paraná and Santa Catarina, Brazil. In both studies, most of them contained barbatic acid and 4-O-demethylbarbatic acid.[16] Barbatic acid is cytotoxic, and kills the worms of Schistosoma mansoni in in vitro studies. This is the causative agent of Schistosomiasis.[17]
Species
Revisions of Cladia published in 2012 and 2013 included 23 species in the genus.[18][19] As of December 2020[update], Species Fungorum accepts 20 species in Cladia:[20]
